The 2026 development

Google described workflows that use information from one app to perform a task elsewhere.

The governance gap

Cross-app context is where personal data leaks into a tool call. The agent needs the fact, not the whole inbox, and the destination should receive the minimum necessary.

Where CAIN-42 fits: Moat 2 — Security-Context Continuity

Core question: Does authority survive every boundary? Identity, scope and delegation are carried across tools, agents, memories and systems.

Apply purpose limitation at retrieval: the agent gets a scoped, minimised context object with a provenance tag, and the destination call is checked against the purpose it was granted.

How the wiring works

  1. Resolve the task's purpose and the minimum data needed.
  2. Retrieve a scoped context object rather than raw app data.
  3. Check the destination against the purpose and the user's grant.
  4. Record which fields crossed which boundary.

What is real today

LIBRARY Production code and tests exist in this repository; there is no hosted route for this exact use.

Purpose-scoped memory and identity primitives exist. No mobile OS integration exists here.

Component in this repositoryWhat the module says it is
cain/argus/memory_firewall.pyCAIN ARGUS — memory-to-authority firewall (Prompt 14, section 12).
cain/memory.pyCAIN Governed Agent Memory & Vector Sanitization SDK (Channel 11)
cain/spiffe.pyCAIN Trust Fabric - SPIFFE / SPIRE Workload Identity Bridge (Phase 3)

Descriptions are the first line of each module's own docstring, read without importing it. A module path is a pointer into this repository, not a hosted endpoint. Its existence is checked by the test suite; its status for this use is the label above.
